Sony has announced firmware version 3.30 for the PlayStation Portable that gives users Wi-Fi capabilities at over 7,000 T-Mobile US HotSpots (from Starbucks to Border bookstores to over 70 major airports). The free Wi-Fi access will be available for six months, after which T-Mobile will give PSP owners the chance to purchase a subscription at a discounted rate. PSP owners must log-in to the T-Mobile HotSpot Network by March 28, 2008 to gain access to the six-month promotional period. The first game title to take advantage of the PSP's Wi-Fi functionality is Ratchet and Clank: Size Matters. The firmware 3.30 update also includes an upgrade that allows PSP users to view videos saved on a Memory Stick Duo in full resolution. As well, thumbnail files for video and RSS content can now be displayed. The firmware updates can be downloaded directly to a PSP wirelessly, downloaded to a PC and transferred to a PSP or installed using upcoming UMD software. Peter Dille, senior vice president of marketing at Sony, said: "The new offer enables Sony to take portable gaming and entertainment to a new level of mobility and convenience for PSP owners."
